Rosanna Arquette will guest star on Private Practice, according to TV Guide.

The 50-year-old, who appeared on another Shonda Rhimes-produced program, Grey's Anatomy, as an inmate who some fans may remember jeopardizing her health to evade solitary confinement, will be playing the bohemian mother of Dink (Stephen Lunsford).

Oh yes, Dink is coming back. We met him on last week's double episode as Maya's new boyfriend. Maya is the daughter of Sam (Taye Diggs) and Naomi (Audra McDonald).

Arquette, who recently guest-starred on two episodes of ABC's Eastwick, is scheduled to appear in one episode of Private Practice in early February. Can't wait to see her!

Sadly, we'll be waiting awhile to see anyone at Oceanside Wellness (or Pacific Wellcare) The show is off until January 14, when it returns with Grey's in a two-hour crossover.

Rosanna Arquette is coming to Private Practice.
